Implementations

impl Source

pub fn config_sources( path: &Option<PathBuf>, ) -> impl Iterator<Item = (&'static str, Self)>

Iterate through valid sources of configuration, in priority order (highest to lowest):

1. path, passed as a CLI argument/environment variable
2. .topiary/languages.ncl (or equivalent)
3. ~/.config/topiary/languages.ncl
4. OS configuration directory (if different from #3)
5. Built-in configuration: Self::builtin_nickel

pub fn queries_dir(&self) -> Option<PathBuf>

Return expected query directory associated with the source path

pub fn languages_file(&self) -> Option<PathBuf>

pub fn fetch_all(file: &Option<PathBuf>) -> Vec<Self>

Return all valid configuration sources. See Self::config_sources.

pub fn languages_exists(&self) -> bool

Checks if a given Self variant can be found as a path or value

pub fn fetch_one(file: &Option<PathBuf>) -> Self

Return a valid source of configuration with the highest priority. See Self::config_sources.

pub fn read(&self) -> TopiaryConfigResult<Vec<u8>>
